Finding error coins is one of the most thrilling parts of coin collecting. These unique coins, which result from mistakes during the minting process, often have fascinating stories and can be worth a lot of money. Let’s dive into what makes error coins special, how to find them, and a list of the most valuable error coins in U.S. history.
What Are Error Coins?
Error coins are coins with flaws caused by mistakes during their production at the mint. These mistakes can happen at different stages of the minting process, and they make the coins stand out from regular currency. Collectors prize these coins because they are rare and unusual.
There are three main types of error coins:
- Planchet Errors: The planchet is the blank piece of metal used to make a coin. Mistakes like clipped planchets (coins with missing edges) or blank planchets (where no design was stamped) fall under this category.
- Die Errors: A die is the tool that stamps designs onto a coin. Flaws in the die can create errors like doubled designs or mismatched dies, known as “mule” coins.
- Strike Errors: These happen when the stamping process goes wrong, such as coins struck off-center or on the wrong-sized planchet.
It’s important to note that only mistakes made during the minting process count as errors. Damage that occurs after the coin leaves the mint doesn’t make it an error coin and holds no special value.
How to Find Error Coins
While finding error coins in circulation is rare, it’s not impossible. These errors usually occur in batches during a particular production run, meaning there are hundreds or thousands of similar flawed coins. Here’s how to increase your chances of finding one:
- Check Your Pocket Change: Always examine your coins for anything unusual. Some errors are easy to spot, but others might require a magnifying glass.
- Search Coin Rolls: Banks offer rolls of coins that you can purchase at face value. Sorting through these rolls can be a great way to hunt for errors without spending extra money.
- Cherrypick at Sales: Look through coin lots at estate sales, flea markets, or coin shops. You might spot a hidden treasure among the more common coins.
Patience and a sharp eye are key to discovering error coins. Knowing what to look for—like specific famous errors—can help you identify valuable finds.
